This page tries to exhaustively combine tags for all pairings of HTML elements
to answer the following questions about how HTML browsers parse tag soup:</p>
<ul>
  <li><a href="#nests-in-body">Which elements can appear directly in the body of an HTML document?</ad></li>
  <li><a href="#can-contain">Which elements can nest directly in which other elements?</a></li>
  <li><a href="#text-content-model">Which elements can contain text content, comments, entities?</a></li>
  <li><a href="#containment-stack-json">Which elements can be introduced between the body and an element
      to allow it to nest properly?</a></li>
  <li>Which elements are implied by which tags? (TODO)</li>
  <li><a href="#explicit-closers">Which open tags close which other elements?</a></li>
  <li><a href="#closed-by-close">Which close tags close which elements?</a></li>
  <li><a href="#closed-by-open">Which open tags close which elements?</a></li>
</ul>

<p>A <a href="#result-dump">JSON dump</a>
   of the results is available at the end once running is done.</p>

  <li><a href="?rerun&shortlist"><tt><span class="basename"></span>?rerun&amp;shortlist</tt></a> &mdash;
      Rerun experiments on the browser instead of using the canned results from Chrome,
      but with a short list of elements instead of the full 128+ HTML elements
